All is very subjective, so any opinion on a version of bandsaw will very much depend on the needs of the user... I have a jet 14" vertical wood bandsaw with a jackshaft to slow it down for metal use, nice for thinner metal, I have one of the popular 4x6 variant horizontal bandsaw, good for heavier cuts, works nice for any materials I use it on, I have a couple chopsaws, as everyone mentioned, noisy, messy, lots of sparks, not very accurate...
I don't own one, but those little bandsaw chopsaws look like they would really be a great solution, unless you would like to do alot of scrollsaw type work, than I would consider the 4x6 horizontal/vertical or the portable with a swag off-road table.
Hand grinders may be an option, though they have more negatives than positives based on what info has been given
